The bar graph given below shows the foreign exchange reserves of a country (in million US $) from 1991 - 1992 to 1998 - 1999.
2:6
3:4
3:5
4:4
Correct answer is C
Average foreign exchange reserves over the given period = 3480 million US $.
The country had reserves above 3480 million US $ during the years 1992-93, 1996-97 and 1997-98, i.e., for 3 years and below 3480 million US $ during the years 1991-92, 1993-94, 1994-95, 1995-56 and 1998-99 i.e., for 5 years.
Hence, required ratio = 3 : 5
The bar graph given below shows the sales of books (in thousand number) from six branches of a publishing company during two consecutive years 2000 and 2001.
Sales of Books (in thousand numbers) from Six Branches - B1, B2, B3, B4, B5 and B6 of a publishing Company in 2000 and 2001.
Total sales of branches B1, B3 and B5 together for both the years (in thousand numbers) is?
250
310
435
560
Correct answer is D
Total sales of branches B1, B3 and B5 for both the years (in thousand numbers)
= (80 + 105) + (95 + 110) + (75 + 95)
= 560.
The bar graph given below shows the sales of books (in thousand number) from six branches of a publishing company during two consecutive years 2000 and 2001.
Sales of Books (in thousand numbers) from Six Branches - B1, B2, B3, B4, B5 and B6 of a publishing Company in 2000 and 2001.
What is the average sales of all the branches (in thousand numbers) for the year 2000?
73
80
83
88
Correct answer is B
Average sales of all the six branches (in thousand numbers) for the year 2000
= 1/6 x [80 + 75 + 95 + 85 + 75 + 70] = 80.
The bar graph given below shows the sales of books (in thousand number) from six branches of a publishing company during two consecutive years 2000 and 2001.
Sales of Books (in thousand numbers) from Six Branches - B1, B2, B3, B4, B5 and B6 of a publishing Company in 2000 and 2001.
75%
77.5%
82.5%
87.5%
Correct answer is D
Average sales (in thousand number) of branches B1, B3 and B6 in 2000
= 1/3 x (80 + 95 + 70) = ( 245/3 )
Average sales (in thousand number) of branches B1, B2 and B3 in 2001
= 1/3 x (105 + 65 + 110) = ( 280/3 )
Therefore Required percentage = [ (245/3)/(280/3) x 100 ] % = ( 245/280 x 100 ) % = 87.5%

= [ 150/205 x 100 ] %
= 73.17%.
